进程和线程模块下都有队列类。

 

线程队列：

# 后进先出->堆栈q=queue.LifoQueue(3)# 优先级队列,数字越小优先级越高q=queue.PriorityQueue(3)

 

进程队列：

JoinableQueue示例：

import time,randomfrom multiprocessing import Process,JoinableQueuedef producer(name,q):    count= 0    while count<3:        print('making,,,,')        time.sleep(2)        q.put(count,block=True,timeout=3)        print('Producer %s has produced %s baozi'%(name,count))        count += 1    q.join()   # 直到队列清空，程序才会结束def consumer(name,q):    count = 0    while count <3:        time.sleep(1)        if not q.empty():break        data = q.get()        print(data)        print('consumer %s has eat %s baozi'%(name,count))        count +=1        q.task_done()if __name__ == '__main__':    # 容器    q = JoinableQueue()    # 生产者们    p = Process(target=producer,args=('A',q,))    p.start()    # 消费者们    c = Process(target=consumer,args=('B',q,))    c.daemon = True    c.start()    p.join()
